Abstract

PURPOSE:To perform the predicting display of the lifetime of a battery by arranging a rotor which drives a battery lifeime predicting display board between the poles of a stator in addition to a rotor which drives a wheel train of a watch. CONSTITUTION:When an inversion pulse signal is supplied to a coil 4, rotors 8, 9 stepwisely rotate in directions of arrows. A gear 14 of the rotor 8 drives a gear 15 and further drives hour and minute hands via a wheel train. At this time the gear 16 of the rotor 9 drives a gear 17 to alternately present the color classified parts on the upper surface of the gear 17 in a window hole 18, thereby carrying out a second flash. While the second flash can be observed through the hole 18, the voltage of the battery is sufficient and means that a watch normally operates. When the voltage of the battery is then lowered, since the minimum starting voltage of the rotor 9 is set larger than the rotor 8, the rotor 8 will still operate to drive the watch, but the rotor 9 will stop rotating. Thus, the second flash is vanished in the hole 18, thereby predicting the vicinity of the lifetime of the battery.
